So, the track will likely end up being LPCM 2.0, or something like that?
Yes. Even if the audio turned out to be Dolby Surround encoded it would still be
captured as LPCM 2.0. The decoding to surround occurs during playback by the users’ receiver.
The digital audio on laserdisc is always 16 Bit 44.1 kHz LPCM. The analog audio can be
captured any way you want. I will capture it at 24 Bit 96 kHz.
Now I’m just hoping that the laserdisc has the original theatrical soundtrack.
